Asked how much it cost to leave the group, he said: "A lot. Somewhere in the low millions. I couldn't give you an exact figure. Who knows? But it's not something I get up in the morning and moan about. It's just what happened. At the time, money was the last thing on my mind."

And Glen insists he was only ever paid £25 a week to be in the band until the royalties started flooding in.

He added: "My wage when I was in the band was only ever £25 a week. But then, a couple of years later, I started getting royalties. In 1979 I remember the letterbox rattled and in came a songwriting royalties cheque for £14,500 .

And when we reformed in 1996 we did a reunion tour and I earned a lot from that. It worked out at £35,000 profit per person per show, and we did the best part of 100 shows, plus we'd get merchandising money and other things on top."
